It seems that as of 11/1/2010 this NPC is stuck too far underground for any possible way to engage in combat to obtain the quest item.

Have killed this mob over and over again with no loot. Dropped quest twice and reloaded ui....hopefully wasn't too important in the chain of things in Uldum. BTW, could loot his twin.

There is definitely a bug but I got the stones in the end, so in case it helps anyone else:

On my first kill I got error "you don't have permission to loot that" and on subsequent kills the moneybags mouse icon stayed grey (on both colussi). I gave up and left the area but couldn't loot the next mob either. Restarted WoW (/reload ui didn't help) and could loot again. Went back to the colossus and killed each fast enough so it hadn't respawned and got the stones fine.

My advice is to kill them very quickly, and if it bugs then restart (or probably just relog). Good luck!
